Beschreibung
Zusammenfassung:Valves configured to induce a pressure drop in a subject fluid may include an inlet, a seat, an outlet, and a valve trim located around the seat and interposed between the inlet and the outlet. The valve trim may include an annulus including a monolithic, unitary, porous material defining a tortuous, interconnected space extending radially through the annulus. Pores at an exterior of the monolithic, unitary, porous material being arranged in a close-packed hexagonal space lattice. La présente invention concerne des soupapes configurées pour induire une chute de pression dans un fluide sujet, lesquelles soupapes peuvent comprendre une entrée, un siège, une sortie, et des pièces internes situées autour du siège et interposées entre l'entrée et la sortie. Les pièces internes peuvent comprendre un anneau comprenant un matériau monolithique, unitaire, poreux définissant un espace tortueux, interrelié, s'étendant radialement à travers l'anneau. Des pores au niveau d'une partie extérieure du matériau monolithique, unitaire, poreux sont agencés en un réseau spatial hexagonal compact.
